Corresponds better to the validation done in other modules of PSA Crypto.

The aead_encrypt and aead_decrypt are lightly
simplified and tweaked versions of test_suite_psa_crypto
test functions with the same names.

Add library/*.h to the list of files scanned for enums in
list-enum-consts.sh, consistent with the changes made to
list-macros.sh.
This is needed to ensure that check-names.sh passes for the MPS
trace enums.

Capitalise the MPS trace macros, as per the coding style (and make a slight
change to naming convention to avoid a name collision).

This was a mistake, there's no reason for the dependencies to be
commented out. The dependencies on PSA_WANT_ALG_EDDSA aren't actually
necessary at the moment, but they might be in certain configurations
if some macros are simplified to save code size.

As we want to do Mbed TLS aead operations as a
driver does, aead operations should not access
the key slot as key slots are not available to
drivers.
Second step in this PR: do not unlock the key slot
as part of operation abort.

First step in this PR: move key resolution from
aead operation setup to psa_aead_encrypt/decrypt

Fix the subtraction in fix_negative, which was incorrectly not looking
for a carry. This caused the result to be wrong when the least
significant limb of N was 0. Fix#4296.
The bug was introduced by d10e8fae9e
"Optimize fix_negative". Thanks to Philippe Antoine (catenacyber) for
reporting the bug which was found by his EC differential fuzzer.

This header file will contain declarations of functions that are not
part of the public ABI/API, and must not be called from other modules,
but can be called from unit tests.

Write a simple unit test for mbedtls_ecp_muladd().
Add just one pair of test cases. #2 fails since PR #3512. Thanks to
Philippe Antoine (catenacyber) for the test case, found by ecfuzzer.

Move the handling of the sign out of the base-specific loops. This
both simplifies the code, and corrects an edge case: the code in the
non-hexadecimal case depended on mbedtls_mpi_mul_int() preserving the
sign bit when multiplying a "negative zero" MPI by an integer, which
used to be the case but stopped with PR #2512.
Fix#4295. Thanks to Guido Vranken for analyzing the cause of the bug.
